-Be iat known that-I,"JoHN PERRY Caos;

Tiiu'ai'ir. a citizen of the United States, and

residentV of Sadieville, in thecounty of Scott and State of Kentucky, have invented'al certain'neav and useful 'Perinutation-Lock, 'ofv which the following is a full, clear, andV exact description.

The objects .which iny invention has in view :we: to provide a lock of the character Vdescribed, wherein the combination .may be ,worked by sound; to simplify and cheapen r the construction; to provide a. lock wherein the combination may be easily andquickly' altered; to providea lock having a combination so simple as to be easily memorized p for fannily use, and thus obviate the need for pass keys.

' Reference is-to bei had to the 'accompany-z ing drawings forming a part of this specicationi, in which similar diameters of reference indicate corresponding partsA in all the vieiws. a I

Figmre l is an isometric `perspective of a lock coinstructedA in accordance with my in hventioni; Fig. 2 is a vertical section of the lock ense,.showing the'permutation wheels and push bar in full lines, and the parts be- `ing in :the locked position; Fig. 3 is a View to be nniderstood as limiting my invention to such application. The (operation of the lock depends prii-.arilv on three elements, which are, the bolt,

the push bar and the permutation rings. Until tlhese elements are Vbrought into-'certain prositions, they will not copeiate. Thus. tlhe bolt. Avis mounted in guide loops B. B'anrd is normally forced forward into a locking position b v a spring C. It is liniaild-.s metracte-dl fi'onithe loekingor forward Dostioni bv the push bar pushing Vagainst a ing E fand the kspring C.

y i shaft G, which .is normally drawn within the lock case by a spiral spring y The normal position of 'the knob I, the shaft G and ush bar F, is shown inFig. 5 of the drawings. In this osition, the push bar frombeing .drawnto the 'level of the lu E .bya standing flan e K, vwhich is hig er than the said lug. t 'the point nearest the so,Y

F passes above the. iig E when the knob i and shaft are rotated. Except in the one position of the push bar, it is lprevented.

bolt .Af-an opening L is made in the flange K,

which opening is large enough to admit the push bar and to permit it to swing against the lug E. and to retract the boltv A. The

push bar F can assume the position in the `opening L only 'when the rinutation rings -M vand. N arein the osition shown in Fig.- 3 of the drawings; w erein openings O and Pin the ri the other an bothpwith the opening L in the flange K. OtherwiseA the one or the;

other of the rings interpose and. prevent the push bar F being depressed into the pat-h of the lug The rings M and N are equal in height, .and are'independent exce t when so moved that the extensions R an S are en gaged. The push bar F is moved to impinge upon the pin T or thepin X, accordying as the said ush bar is moved to the right 'or left, re erring to 'the illustration shown in Fig. 3 of the drawings. The rings n M and N are provided with annular Hanges U and V (see Figs. 5 and 6), which prevent a the` dislodgnient of the rings by extending into grooves formed in the fra-ine struct-ure of the lock. Thesegrooves arel formed in 4the side of the flange K, and in the partition V2. VThis arrangement prevents dislodginent of the rings M and N. The ring M is also provided with holes W' intok which the pins T and X are fitted. It is' by setting these pins T and X that the combination is varied. Corresponding with the holes lV are the click points Y on a sounding wheel Y,l mounted 'on the shaft G. Hence every point of the sounding wheel Y coincides with the spaces between the said holes. The action of the wheel Y is steadied and the movement is "nnounced by the clicking of a detent Z. ihus thevnuinber itt-d in ;ts forward movement by a lug D, i of clicks of the detentaudibly indicates the dislaneeof rotation of the shaft G. The

`detent Z is mounted in guide loo s a end b.

The loop a is elongated to permit a lateral 'action konl the part of the detent.' de.

'is i 'i .M and N register each with l tent is controlled bythel springs o and d,

the former of .which forces the detent f against the wheel longitudinally, while .the

- with a loud click. .The sounding wheel Yi latter forces it against the wheel laterally.. When the wheel is moved infeit-hcr direction Y the` detent over-rides the points of 'the soundingwhe'el and-falls betweenv the'points and detent Z are mounted between the walls the free 'end'of afspring It. The free end,

e and eof the lock casing.

Thefshackle A is pivotally mounted at f,

l and is provided at Vthe reeend with a recess to receive'the'end of the bolt A'. The pivoted end of the shackle is provided with a hook-like extension g, to engage and hold of the spring l1. is bent over and behind the extension g, as seen in Figs. '2, 3, 4 and 5.

- for the removablek cover sz'.

vWhen the'bolt A is withdrawn from engagement with `the shackle, the spring yIt lift-s the free end of the'shackle by pressing upon the hook g of the shackle to rotate the same on its pivot. The opposite end of the spring It is tixedly attached to the removable cover d (see Fig. 5).' The spring IL serves the double purpose of throwing the shackle from the locked position, and that of a lock The spring is constructed and arranged in such manner that when the shackle A is placed in the locking position, the spring lz. is nioved from its normal position and under tension.

When the shackle A Ais free, the spring la l` is released from engagement with the hook g, and the cover 'a' may be drawn downward to uncover the permutation rings and parts connected therewith. The cover -i is guided in the grooves, m, m formed inthe edges of the sides of the casing for the lock. (See spring h is engaged by the hook g passingl Figs. 5 and 6 of the drawings.) The cover z" being removed, the rings M and N andthe pins T and X are exposed. The combination may then i be changed asdesired. Whenever the cover is placed in position, and the shackle A is snapped into ,locking relation with the boltr A, the bent end of the har F impinges upon the'pin T and thereliyV moves the ermutation ring M to the right.

The extension R ofthe permutation ring M engages the extension Supon the permutation ring N, causing the said rings to; thereafter move together, while continuingl to counted yuntil' the sameimpiuges upon the 'casses Y insegni. Thev imdb I .-is'amwn entend until the push'bar F ri'des onth'e 'upperedge of the flange K.' The continuation of the rotation of the ,push bar F to the right causes the same to strike upon and to be arrested by the projection K2 extended from tacts with the' projection K2itwill be foun'd A 'that the permutation rings are arranged as" shown 1n F 1g. 2 of the drawings. This is the'starting point for the working of the-l'1i combination of the lock. The knob I is released so that the spring H returns Vto its initial position, in which it will pass over thevr projection K2 whenmoved to the right. The rotation is continued in the said.

direction, carrying the push bar F to the right, as seen 1n Figs. 2 and 3 of the draw- A' ings The bar F, still engaging the pin T,

and the projection R still en -frinfthe pror` 1 jection S, the permutation rigisilggs :ihre moved 85; i

to the right until the opening P in thering N is ahned with the vopening vL Vin the ange K. This alinement of the opening P with the opening L has been effected, by

It will be noticed that it 'is necessary tu points Y of the wheel Y. The detent Z,

permutamove the pin T four spaces to thev right of -the opening L to aline the opening P therewith. These four spaces on thel tion rings correspond to four of the click Y striking upon the said click points of-thefv i wheel Y, reduces resonant clicks, which are y the operator. When he has counted four, after having been arrested by the projection K2, he knows that so much of the combination has been-perfected. The

knob I is now turned in the opposite direction, carrying the push bar F to the leg in. n

ins

The operator, counting the number o clicks and havin his forrnlila, continues to move the knob to carry the push rod' F to the left. until the correct number of clicks has been sounded. At this point, he Yarrests the rotation' of the knob -Accordin' to the combination, as illusiin trated in the drawings, after leaving the' pin T four spaces to the right of the opening L, and the opening O being at that timelone space to the right of the opening L, A

it is necessary to move the knob I in the" vreverse direction eight spaces. It requires y a movementl of seven spaces inthe reverse vdirection before the bar F impmges upon the pin X. {The only further movement after this impingement moves the ring M one sgace to the left, and 'places the opening f y ring M, moving to the left, does not move will be found to have been ahned.

It' now necessary tomove the bar F over the :dined openings L, O` and P, and to in line with the opening L. .The 12.5

c the rin N,and hence tle three-openings v L O and means of the wheel Y and the VdetentZ. 9,0*

openings L, O and I. The bar F may now be drawn dowiiinto the openings'by' pulling ontward the knob I. In the'deprsed position ofthe bar F theV end thereof is ex tended in front of the lug E. By now moving the bar F to the left, the. bolt A is moved out of engagement with the shackle ajspriugli.

The combination in the above opera- 'tion'fater the preliminary rotation to the right, and being arrested, is: to the right four spaces; to the left ei ht spaces; and to the right four spaces. -Vien the combination is vbeing operated by count of the audi-l ble sounds, then it will be understood that `thesounds will guide instead ofY the spaces, as stated above. The combination may be changed at any time by moving the pinsT and X, or either of them. 1

In referring to the direction for moving the knob I and push bar F, in the above deseription, it is intended that the description s shall be read 'upon the Figs. 2 and 3, that is,

A', andthe said shackle isvsprung by the right as moved on Fig. 2. v

.As above stated, the spaces between the .holes W coincide with the click points of the sounding wheel Y, and .the detentZ, on passtor. Therefore the spaces are, in this lock, indicated by the sounds thus produced. By this arrangement-the combination may be worked in the dark as readily as in the light.v Should the combination become known, or the owner Yof the lock be suspicious of this fact, the combination may be quickly changed by removing the cover 'i of the lock easing and then changing the location of one or both of the pins-T and X.

'While I have herein described the employ- A ment in this construction of the two pins X and T, it. is obvious that the lock may be operated by omitting one of the said pins. This omission would rrerel'y necessitate the further movement of the handle and push bar connected therewith.

Having vthus described my invention, I
